Project Management Committee

Sedona has received numerous help from the community. This page lists the contributors and committers of Apache Sedona. People on this page are ordered by their last name.


A contributor who contributes enough code to Sedona will be promoted to a committer. A committer has the write access to Sedona main repository

Project Management Committee (PMC)

A committer will be promoted to a PMC member when the community thinks he/she is able to be in charge at least a major component of this project.

Current Sedona PMC members are as follows:

Become a committer

To get started contributing to Sedona, learn how to contribute – anyone can submit patches, documentation and examples to the project.

The PMC regularly adds new committers from the active contributors, based on their contributions to Sedona. The qualifications for new committers include:

  • Sustained contributions to Spark: Committers should have a history of major contributions to Sedona.
  • Quality of contributions: Committers more than any other community member should submit simple, well-tested, and well-designed patches. In addition, they should show sufficient expertise to be able to review patches.
  • Community involvement: Committers should have a constructive and friendly attitude in all community interactions. They should also be active on the dev mailing list & Gitter, and help mentor newer contributors and users.

The PMC also adds new PMC members. PMC members are expected to carry out PMC responsibilities as described in Apache Guidance, including helping vote on releases, enforce Apache project trademarks, take responsibility for legal and license issues, and ensure the project follows Apache project mechanics. The PMC periodically adds committers to the PMC who have shown they understand and can help with these activities.

Currently, Sedona makes committers PMC members automatically.

Nominate a committer or PMC member

Steps are as follows: 1. Call a vote (templates/committerVote.txt) 2. Close the vote. If the result is positive, invite the new committer.

Call for a vote

We do the vote and discussion on the to enable a frank discussion. Please read ASF Incubator New committer Discussion for notable items.

Let the Vote thread run for one week. A positive result is achieved by Consensus Approval: at least 3 +1 votes and no vetoes.

PMC vote template

Voting ends one week from today, or until at least 3 +1 votes are cast.

Send a notice to IPMC

The nominating PPMC member should send a message to the IPMC ( with a reference to the vote result in the following form:

To: private at
CC: private at
Subject: [NOTICE] New PMC NAME for Apache Sedona PPMC

New PMC NAME has been voted as a new member of the Apache Sedona PPMC. the vote thread is at: *link to the vote result thread*

Note that there is a grace period of 72 hours from when the PPMC sends the NOTICE to the IPMC to when the PPMC should formally invite the proposed member. This is an important part of the overall process. Failure to do this can result in an embarassing situation for people involved.

In recognition of your demonstrated commitment to, and alignment with, the
goals of the Apache Sedona project, the Sedona PPMC has voted to offer you
membership in the Sedona PPMC ("Podling Project Management Committee").

Please let us know if you accept by replying to this email 

The PPMC is the Incubator podling version of a project PMC ("Project
Management Committee") that for every top-level project is tasked by the
Apache Board of Directors with official oversight and binding votes in
that project.  When Sedona graduates from the Incubator to a top-level
project, the project PMC is usually formed from the membership of the PPMC.
Note that while participation in the PMC after graduation is not
guaranteed, simply continuing your constructive and active participation
is usually sufficient.

As a PPMC member, and later as a PMC member, you are responsible for
continuing the general project, code, and community oversight that you
have exhibited so far.  The votes of the PPMC are not legally binding;
votes of the Incubator PMC are.  However, many of the PPMC members
are also Incubator PMC members, so they implicitly cast binding votes
when we vote on PPMC issues.  While this is an important legal
distinction, it shouldn't enter your thinking when working on the PPMC -
members should treat every decision as if it were legally binding for the
 ASF. Also, in day-to-day activities, the Incubator PMC member vs PPMC 
 member distinction should be invisible -- we are peers.

Finally, the PPMC (and assuming graduation, the PMC) is not meant to create 
a hierarchy within the committership or the community.  In fact, a goal is 
to add all committers over time to the PPMC/PMC, as our belief is that those 
who do the work should get a binding vote.  Therefore, in our day-to-day
interactions with the rest of the community, we continue to interact as
peers, where every reasonable opinion is considered, and all community
members are invited to participate in our public voting.  If there ever
is a situation where the PMC/PPMC's view differs significantly from that 
of the rest of the community, this is a symptom of a problem that needs to
be addressed.

With the expectation of your acceptance, welcome!
